DATASHEET

Figure 4.3 shows a system configuration in which the UCS1001-1 provides a port power switch, low

power Attach Detection, charger emulation (with no USB host), and charging active signaling.

Figure 4.4 shows a system configuration in which the UCS1001-2 provides a port power switch, low

power Attach Detection, charger emulation (with no USB host), and portable device Attach Detection

signaling. These configurations are useful for wall adapter type applications.
